Question

Oxidation is the process in which an atom or a group of atoms taking part in a chemical reaction loses one or more electron.

• A. True
• B. False

Answer 1

The correct option is A

True

We know the general definition of oxidation.

oxidation is the process of addition of oxygen or any electronegative element or group or removal of hydrogen or any electropositive element or group . for example:

a. $2Mg\left(s\right)$ + $O_2\left(g\right)$ $\stackrel{\left[O\right]}{⟶}$ $2MgO\left(s\right)$ (Addition of oxygen)

b. $2FeC{l}_2$ (aq) + $C{l}_2$ (g) $\stackrel{\left[O\right]}{⟶}$ $2FeC{l}_3$(aq) (Addition of electronegative element)

c. $H_{2}S$ (g) + $C{l}_2$ (g) $\stackrel{\left[O\right]}{⟶}$ $2HCl\left(g\right)+S\left(s\right)$ (Removal of hydrogen)

d. $K_{2}Mn{O}_4\left(aq\right)$ + $O_3\left(g\right)$ + $H_{2}O\left(l\right)$ $\stackrel{\left[O\right]}{⟶}$ $KMn{O}_4\left(aq\right)$ + $KOH\left(aq\right)$ (Removal of electropostive element)

Now, Let's take a look at the electronics concept of oxidation.

Oxidation: It is a process in which an atom or a group of atoms taking part in a chemical reaction loses on of more electrons, For example :

$Mg⟶M{g}^{2+}+2e^{-}$
